HIGH FREQUENCY DEVICES
DIELECTRIC RESONATORS–DRD & DRT
F Series
GENERAL CHARACTERISTICS
I
High unloaded Q — 35,000 min. at 10GHz
I
High dielectric constant —
r
24
I
Resonant frequency temperature coefficient can be chosen
from 0 to 4ppm/°C. Tolerance of frequency temperature
coefficient can be chosen from ±1, ±2ppm/°C.
I
Dielectric resonators which operate in the range of
10–25GHz can be selected in DRD (disk) or DRT
(coaxial) form.
I
F-series is also fit for application above 25GHz. Please
consult us.
